<p>I am a South African who got an interview, and can share what I know (Sure it is applicable in India too?)</p>
<p>If you got an interview they need more info. If you didn’t, there are 2 options. </p>
<p>1) You are not good enough and are rejected.
2) You are good enough and accepted.</p>
<p>An interview is for people who are possibly good enough to be accepted, but they need more info about (to get them off the fence) or in my case (I think) because they had some specific questions about my life, and what I submitted in my application.</p>
<p>So, yes, if you got an interview it is a good sign; you have not been rejected yet, but if you didn’t you may already have been accepted. Overall, I would guess that people who get interviewed are <em>slightly</em> more likely to get in. Perhaps though that is my hopeful assumption.</p>
